Same frontal and style as the Pile Shirt, but the fibre material pile has been replaced with a layer of the Softie insulation, Re-flecta-therm and the T.S.1 giving the same performance, with a lighter more compact unit, something to think about if you don't intend on using the garment 100% of the time. A neck collar come baffle the same as the sleeping bag one has also been used to seal the collar. Comes with a stuff sack.
